The spots are in small clusters along both sides and top and are all located on the carpace (front end?) The shrimp is a scarlet that we've had aprox. 3 weeks. The same day we noticed the spots, we noticed that the inside of her abdominal area was light green, different than before. She was hanging upside down, beneath a rock, and seemed to be "picking" the green out with her feet. We thought they might be eggs but we're not sure.
